DTC U0078-88: Control Module Communication Bus "F" Off - Bus off: Action

WARNING: This page is about a different car, the 2023 Jaguar F-Pace and 2022 Jaguar F-Pace. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Do NOT replace the anti-lock brake system control module. The anti-lock brake system control module has lost synchronisation with the FlexRay bus. This may be due to vehicle harness connections or harness integrity

Refer to the electrical circuit diagrams and check the FlexRay bus circuit for short circuit to ground, short circuit to power, open circuit, high resistance
